        <h2>Description</h2>
        <p>
      Audio output is a tone related to the striking of a metal block as found in a vibraphone. The method is a physical model developed from Perry Cook, but re-coded for Csound.

        <h2>Initialization</h2>
        <p>
      <span class="emphasis"><em>ihrd</em></span> -- the hardness of the stick used in the strike. A range of 0 to 1 is used. 0.5 is a suitable value.
    </p>
        <p>
      <span class="emphasis"><em>ipos</em></span> -- where the block is hit, in the range 0 to 1.
    </p>
        <p>
      <span class="emphasis"><em>imp</em></span> -- a table of the strike impulses. The file <a class="ulink" href="examples/marmstk1.wav" target="_top"><em class="citetitle">marmstk1.wav</em></a> is a suitable function from measurements and can be loaded with a <a class="link" href="GEN01.html" title="GEN01"><em class="citetitle">GEN01</em></a> table.

    </p>
        <p>
      <span class="emphasis"><em>ivfn</em></span> -- shape of tremolo, usually a sine table, created by a function
    </p>
        <p>
      <span class="emphasis"><em>idec</em></span> --  time before end of note when damping is introduced

        <p>
      <span class="emphasis"><em>kvibf</em></span> -- frequency of tremolo in Hertz. Suggested range is 0 to 12
    </p>
        <p>
      <span class="emphasis"><em>kvamp</em></span> -- amplitude of the tremolo
